11:50 am
going to change jobs three times, not just jobs, change industries three times in their first decade. that is no. all of the unsettling, scary stuff that produced progressivism was about the idea that job disruption created all of this unsettling ripples into human capital. a lot of what people panicked about now is what we will experience at warp speed for evermore. we will have 40, 45 and 50 euros getinterrupted -- year old interrupted and we will have to create a civilization of lifelong learners. no other civilization has ever done that. >> watch after worse at 9:00 p.m. on sunday. -- afterwords at 9:00 p.m.. >> we look at eugene's unique history. come into museum of natural and cultural history were will hear from dr. dennis jenkins about
11:51 am
his archaeological work which are located about 200 miles southeast of eugene. jenkins: when i was a werent in the 1970's, we taught people had only been here about 11,000 years. well, as time has gone on and certainly with the radiocarbon dating of human dna and copper and the paisley caves, that story begins to come apart. the paisley caves are found in the high desert of central oregon. it is technically called the northern great basin. that is because all of the water nows to the interior and access out to the pacific ocean so it evaporates. it comes from the mountains surrounded it very -- surrounded
11:52 am
it. it was excavated in 1938 and a little bit in 1940. when he was finished, he published and said he had found extinct animals from the ice age, horses and camels that were here, you know, north america before they were actually found in other portions of the world. people hunting these animals and he had found a small -- in the cave with the bones surrounded it. and he said he had proven people were in the northern great basin during the ice age. it did not take long and the archaeologists, professionals asked him, began to question whether or not this was a good
11:53 am
association between the artifacts and in the bones. unfortunately, the excavations had been conducted so hastily that they did not record all of the information they needed to address those questions. --who thousand two, i return 2002, i return to their with the archaeological field school and began work well aware that we had to document the exact locations of the artifacts, as well as the bones. to do was see if i could get the radiocarbon dates on artifacts to overlap those of the camel and horse bolts. -- bones. i did not know at the time what part human copper life would play and that did not come about -- fromout 2005 when
11:54 am
the university of copenhagen in denmark found ancient human dna in some other copper lights i had given him. lab, it is not very fancy, but it does its job. the materials at that we have collected from the paisley caves over the last 10 years, actually. 2002, and so i guess it has been about 15 years. what we are looking at here is our cataloging system. basically, a- equals artifacts and each of the tubs will be artifacts, botanicals, plant matter that we collected. that is what we have here. a is artifacts and of those
11:55 am
classes. c represents a copper life. we have 1800 of them that were big enough that we thought that perhaps they could be human. as you can see, we would , in ated these in the full hazmat outfit so every time lite weuntered a copro have to stop work and put on the hazmat to in an attempt to keep our contamination of getting our own personal dna in molecular form into a coprolite of this age. and so, it is a very slow, meticulous process, expensive. and to some degree, not very green because everything is
11:56 am
individually packaged. ,ust like going into surgery that is the process that we have gone through for each one of youe caught -- coprolites, are seeing here. we collected them, like i said, in a hazmat suit with the white, funny suit and a facemask and two pairs of gloves. nobody really wants to handle them without gloves. all of this is done in a protocol that allows us to really restricting the amount of modern contamination by our own a dna. when we get done, ideally, this coprolite should have been in one of those containers that i showed you and sealed up with all of the information written on the outside. unfortunately, this very
11:57 am
nice-looking humanlike coprolite was found and recorded as being found in the screen, which means it probably was contaminated by the time it was found. so, that allows us on the other hand to bring it out and show and people ask, how can you identify these? -- look prettyh much like a coprolite that fido would leave in the backyard and after they tried out, they become pellets. they are relatively easy to identify in the sediments within the case. -- caves. normally, we would not handle these, but it is already been contaminated. it is the right color. it has a lot of vegetation inside. a does seems to have perhaps
11:58 am
human appearance to this one. we do not know it is human because at this stage, we have not done dna analysis. the significance and beauty of anding coprolites like this being able to identify human dna in them is the fact that that if we had found human remains like ed human flesh, we would not be able to study it because the fact that those human remains are protected by law. and certainly, some native tribes are in agreement that if we respectfully, analysis is done, they will allow it. it is always a sensitive issue. in this case, the native americans cannot throw their
11:59 am
entire -- can throw their entire agreement behind my work because what i am basically dealing with is garbage that has been left behind. yet, it has their dna in it. they are as interested as we are in the story of their ancestors coming here from siberia. so, we have identified groups a, a2, b2 in some of these coprolites from the paisley caves. we know the area of eastern asia that those groups probably originated from during the places means of when they originated and left asian to come to north america. workis a way that we can closely with the native tribes and all of us learned something
